Embodiment 1

[0076] figure 1 It is a schematic flowchart of an image acquisition method provided in Embodiment 1 of the present invention. The method of this embodiment can be performed by an image acquisition device, wherein the device can be implemented by software and / or hardware, and can generally be integrated into an embedded system, which can be applied to the field of automatic driving, and is typically assembled in an in electronic devices such as cars driven by humans. Such as figure 1 As shown, the method may include:

[0077] S110: Collect compressed format images according to the compression parameters of the camera.

[0078] Exemplarily, due to objective reasons such as cost and size, the embedded system does not configure a large memory space for it. Generally, the memory space configured for it is less than 512MB, that is, a small memory embedded system. When using these embedded systems to develop applications with a large amount of data such as pictures or videos, sma...

Embodiment 2

[0095] figure 2 It is a schematic flowchart of a preferred image acquisition method provided by Embodiment 2 of the present invention. The second embodiment refines the configuration of the embedded system and the steps before and after "according to the compression parameters of the camera" on the basis of the technical solutions of the foregoing embodiments. figure 2 , Embodiment 2 of the present invention specifically includes the following steps:

[0096] S210: configure the compression parameters of the camera based on the application programming interface in the video capture framework of the Linux system.

[0097] Wherein, the compression parameters of the camera include a compression format.

[0098] Exemplarily, since multiple functions related to the image cache are provided in the video capture framework of the Linux system, by calling the function and setting corresponding parameters, multiple compression formats other than the compression format can be configu...

Embodiment 3

[0118] image 3 It is a structural block diagram of an image acquisition device provided by Embodiment 3 of the present invention. The device can be realized by software and / or hardware, and generally can be integrated in an embedded system, and the embedded system can be applied in the field of automatic driving. Such as image 3 As shown, the device includes: an image acquisition module 310 , an image storage module 320 , an image decompression module 330 and an image processing module 340 .

[0119] Wherein, the image collection module 310 is used to collect compressed format images according to the compression parameters of the camera; the image storage module 320 is used to store the compressed format images in the internal memory; the image decompression module 330 is used to store the compressed format images in the internal memory; The image in the compressed format is decompressed to obtain the image in the uncompressed format; the image processing module 340 is use...

Abstract

The embodiment of the invention discloses an image acquisition method and device, an embedded system and a storage medium. The embedded system comprises a camera and a memory; the camera is used for collecting an image; and the memory is used for storing the image collected by the camera. In addition, the image acquisition method includes: according to a compression parameter of the camera, a compression-format image is collected; the compression-format image is stored in the memory; the compression-format image is decompressed to obtain a non-compression-format image; and the non-compression-format image is inputted into a deep learning network. Therefore, the storage pressure of the embedded system memory is reduced; problems of the system shutdown during the image collection process andthe memory overflow during the image storage process and the like can be solved; and the processing efficiency of the embedded system is improved.

Description

technical field [0001] Embodiments of the present invention relate to data processing technologies of embedded systems, and in particular to an image acquisition method, device, embedded system and storage medium. Background technique [0002] With the development of science and technology, the image acquisition system with ARM (Advanced RISC Machines, processor) as the main control chip is being adopted by more and more embedded handheld devices. Among them, in the field of unmanned driving, image acquisition systems integrated with binocular cameras are often used. Wherein, the binocular camera collects two images simultaneously through two cameras. [0003] In the prior art, the image input to the neural network for image processing is generally required to be in the original image format. For devices using small-memory embedded systems, the binocular camera needs to collect two left and right images during the image acquisition process, so the memory usage is relativel...
